Linux: Add the pthread_gettid_np function (bug 27880)

Current Bionic has this function, with enhanced error checking
(the undefined case terminates the process).

+This function returns the same value that @code{gettid} would return if
+executed on the running thread @var{thread}.
+
+If @var{thread} is no longer running but it is joinable, it is
+unspecified whether this function returns @minus{}1, or if it returns
